I’d say you should be able to recut them – there’s enough material left, so the nuts and washers should still hold. I’d give it a try at least. If you know anyone who can weld, you might get him to weld some beads on the damaged threads and recut them afterwards.

Chase them and test.
Doesn’t look good but I think you might be able to save it.

Is this the one that had the hanger on the headset? If so, remove it and you will miss most of the damage bits. You may also be able to find the bottom half of a headset which is shallower.
I would also get the head tube faced before a rebuild – if it has been really loose and ovalised you will want to get it sorted out.
All fixable, I reckon.

Take it to a shop that has OLD tools, you need to chase the threads. 90% of the time that works. Otherwise you will need to find a headset with a shorter stack height.
Yes. Chase not cut. If that doesn’t work, have a pro cut out a couple of inches of the tube and (tig) weld on a piece of chrome/moly. The Hail Mary is to use JB Weld. Not even kidding. I’ve fixed dozens of stripped fork tubes with it. The trick is to turn down the die BEFORE you apply the JB. Once it cures, sand and then back the die up the tube STARTING on the good threads.

This is what you need, and why you need to go to a bike shop:
